Beschreibung
Zusammenfassung:	PCT No. PCT/FI94/00387 Sec. 371 Date May 3, 1996 Sec. 102(e) Date May 3, 1996 PCT Filed Sep. 2, 1994 PCT Pub. No. WO95/07254 PCT Pub. Date Mar. 16, 1995The invention relates to a new, technically simple but efficient process, with a good yield, for the preparation of 2-ethyl-1,3-hexane diol from n-butyraldehyde by aldol condensation in the presence of an alkali metal hydroxide or alkali earth metal hydroxide catalyst. To promote the reaction and to improve its controllability, a neutral phase-transfer catalyst is additionally used in the process according to the invention. 2-Ethyl-1,3-hexane diol is used in insecticides and, for example, in the preparation of polyesters.
